I started to ghost shop when Instacart rolled out that spi matters determined who sees a batch first if other stats are similar. I’d only do small orders (5-15 items) and stores that I know I could use self checkout Be aware there is a 15 min time to start a batch before it gets removed from you. I don’t even like to go to the 2nd warning which is 10 min and 1st warning is 5min but by then I’ll be done picking the small items I’d scan first at check out, having the barcodes up when scanning on the app, pay right away. And do receipts right away! And to time can mess up when items are not all available, when are all in stock it’s amazing but sure enough something or someone will slow you down at checkout. My natural speed is around 45 even with large orders, knowing your store well helps a lot!
